Calcium Hardness

[lonestarcj7]

Good afternoon! I have been testing using my test kit and I am watching my Calciuim Hardness climb.

According to the app I need to reduce to 250-350, I am currently at 475. My water supply is 175.

The app says to replace 68% of the water.

I am assume its because the pool was just put in this year. My concern is that I have a flag stone spa spillover and I can start to see calcium forming on it. On that note, any suggestions on how to remove that?

Water looks great and most items seem to be in line.

FC - 6.5
PH - 7.5
TA - 100
CH - 475
CYA - 25
CSI - .24

Thanks!

If you can keep the CSI slightly negative, the scaling can be slowed.

Your CH is not unmanageably high yet.

I also think being in TX, you should raise the CYA up around 50ppm.
